Answer 1

Use FIND_IN_SET

PHP code:

$a=['php','java','.Net']
$query_part = '';
foreach($a as $v)
{
    $query_part .= "FIND_IN_SET('$v',keyskills) OR ";
}
$query_part = trim($query_part, ' OR ');

$sql = "select jobid from jobfair where $query_part";

//select jobid from jobfair where FIND_IN_SET('php',keyskills) OR FIND_IN_SET('java',keyskills) OR FIND_IN_SET('.Net',keyskills);

If you want to return rows that match all values then use AND clause.
